Remarks

The values returned by the properties discussed here are based on the total number of pointer devices connected: Boolean properties return true if one device supports a specific capability and numeric properties return the maximum value exposed by all devices.

The Device Capabilities Sample demonstrates how to detect the presence of input devices and retrieve the capabilities and attributes of each device.
